Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are commonly used in structures that require exceptional adhesion.
Most common temperature resistance of these magnets is 80°C, but with larger dimensions, this value grows.
In addition, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their durability.
The magnet named MPL 20x3x2 / N38 and a magnetic force 1.22 kg weighing just 0.90 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often utilized in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape makes it easier mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators greater flexibility in placing them in devices, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be more appropriate.
Magnets have two poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are regularly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
It’s worth noting that high temperatures can weaken the magnet's effect. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards and even medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field very well,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical equipment and very advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Possible danger to health from tiny fragments of magnets can be dangerous, when accidentally ingested, which becomes significant in the aspect of protecting young children. Furthermore, small elements of these products have the potential to hinder the diagnostic process in case of swallowing.
Exercise Caution with Neodymium Magnets
Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can shock you at first.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
If you have a nickel allergy, avoid contact with neodymium magnets.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets will jump and also touch together within a radius of several to around 10 cm from each other.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Maintain neodymium magnets away from children.
Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnets are especially fragile, which leads to their breakage.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
